EGG-TESTER.

Specification of Letters Patent.

Patented A11 16, 1915.

Application filed June 18, 1914. Serial No. 845,358.

To all whom it may concern: I,

Be it known that I, WALTER E. FnosT, a citizen of the United States,residing at A11- burn, in the county of Androscoggin and State of Maine,have invented certain new and useful improvements in Egg-Testers; and Ido declare the following to be a full, cleaiyrand exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to improvements in egg testers and has for itsprimary object to simplify the construction of devices of this characterwithout sacrificing any of the advantages thereof; in fact, providing adevice which possesses numerousadvantages over other styles of testers.

A secondary object of the invention is to provide a yielding support forthe tester whereby the eggs may be jarred for a purpose to appear.

A. further object of the invention is to construct a light receivingreceptacle in such a manner asto provide a number of light intensifyingsurfaces and to form theupper edge thereof in such a manner as tosupport an egg tray or an egg carrier as the case may be. 1

A. further object of the invention is to construct said egg tray in sucha manner as to allow the same to act, not only as asupport for the eggbeing tested, but for a number oi eggs to be tested.

Further objects of the invention are to provide a simple and etficientshield for use in connection with the device and to provide simple andeilicient means for attaching anelectric socket. I

\Vith these objects in view, the invention resides in certain novelfeatures of construction and combination herein described and claimedand shown in the drawings where in Figure 1 is a side elevation of anegg tester constructed in accordance with my invention; Fig.2 is an edgeviewv thereof; Fig. 8 is an enlarged central vertical longitudinalsection; Fig. 4 is a transverse section taken along the plane of theline 44: V

of ,Fig. .3; Fig. 5 is a sectional perspective View of a portion of theegg tray; Fig. 613%} view similar to Fig. 3 showing the manner in whichthe upper edge of the light receptacle may be employed for the purposeof supporting an eggcarrier; and Fig. 7 is a transverse section takenalong the plane of I post 8 whose upper end is turned laterally toprovide a support for the upper end of the spring 3, the latter beinghere shown as oi the helical type and having its lower end connected asat 9 to one of the lower edges of the bottom 10 of the receptacle 2, theopin general, a base 1, alight receptacle posite edge of said bottombeing hingedlyv connected to the base 1 by any appropriate hinge 11 Byreference to the drawings, it will be seen that the edge of thereceptacle 2, to which thcspring 3 is attached, is yieldingly supportedabove the base 1, but is al lowed to swing around the hinge 11 as thespring 3 yields, a suitable bum-per 12 being preferably provided for thepurpose of preventing excessive downward movement, on the part of saidreceptacle 2. I r i The "receptacle 2 includes the bottom 10 and. anupwardly and outwardly inclining surrounding wall 13 rising therefrom,said wall having its upper portion contracted by inclining the sameinwardly and upwardly as indicated at 14L while the extreme upper edgeof said Wallis provided with the offset portion 5 which is L-shaped incross section,

and which constitutes a support for the tray '6 and likewise foraneggcarrier in a manner to appear. I

By constructing the receptacle 2 in the above set forth manner, a numberof .retlecting surfaces are provided, said surfaces tending to intensifythe rays of light which radiate from an electric bulb '16 which islocated in the receptacle? and is carried by l 7 opening beingpreferably curved downwardly for Obvious reasons. The plate2l issurrounded by an upstanding wall 23 which rises a suitable distance toprovide an egg retaining l 5 reference to the drawings, it willbe seenthat the upper portion of the clamp 18 is united with the wall 13 whilethe lower portion thereof and the ears 19' are free to move plate2l'which is of suitable configuration and is provided with an eggreceiving opening 22 near one end, the materlal around said flange whileits lower portion depends from the-plate 21 and is adapted to engage theouter side of the offset portion 5, when the tray is in positionthereonas seen in Fig. 3,

in which position'said plate 21 is adapted to rest upon the extreme edgeof said offset portion. By this formation of the tray 6, a

number of eggs, indicated at 2st Fig. 3, 'may be retained within saidtray for the purpose of being tested one at a time. It will benoted thatthe tray inclines downwardly and forwardly, this being caused by thefact that the upper edge of the wall 13 is located in a planelying at anacute angle to the bottom 10 and by the "fact that the rear side of thereceptacle 2 is supported at a higher level than the forward sidethereof.

Adapted for use in connection with the device as above described, is theshield 7, the latter being in the form of a continuous flexible Wall25having its lower end suitably shaped to fit within the wall. 23 andbeing provided with a continuous stop 26 whichlimits its "downwardmovement by coming in contact with the upper edge of said-wall 23. Thisshield 7"is preferablyformed of cardboard but it is evident that anysuitable material maybe employed.

With the parts as above described, the operation of the'device is asfollows: The tray 6 is removed fromthe device and may be used for thepurpose of carrying the eggs to be tested from'a crate to the testingde-' vice upon which the same is now arranged as above set forth and asshown inFig. 3.

The entire device is now jarred, this operation being necessary inorderthat the eggs may be jarred therefore rendering the testingoperation more successful as it is a well known fact that eggs maybetested more accurately after shaking j or jarring the same. Itfmay herebe explained however,

that my improved tester is not designed for V testing eggs to vbe usedfor hatching purposes although it may be adapted'to this use H providedno jarring is allowed. In testing the eggs in this manner, the shield 7may be employed if necessary. ,7

In Figs. 6 and 7 I have shown the manner in which the receptacle 2 maybe employed for the purpose of yieldingly supporting an egg carrier 27,the latter'being of commonv constructionand formingno part of thepresent invention. In this connection it will be seen, that the carrier27 rest with I a in theoflset portion and flange thereof. 1 V v From theforegoingdescription taken in upon the horizontal connection with theaccompanying drawings, it will beseen that I have produced an extremelysimple egg testingdevicelyet one which will be highly efficient inoperation and which has numerous advantages over otherdevices'of thischaracter.

I have described my invention with conand yielding means for controllingthe movement of the hinge. I 1 2. An egg tester comprising a lightreceptacle having an egg receiving opening,
